Isang Dakilang Bayang Mahal
Sa atin ay bigay ng Maykapal
Lupa at lahing ikararangal
Noon ngayon magpakaylanman.
Ikaw at ako lahi ay iisa
Sa Castillejos halina
Kayang-kaya kapag sama-sama
Uunlad at giginhawa.
Ang bayan ni Ramon Magsaysay
Itangi at mahaling tunay
Labing-apat Ligang Barangay
Pinag-isa tungo sa tagumpay.
Edukasyon ating linangin
Itanghal sariling atin.
Sa bayan kong minumutya
Mga ngiting nakahahalina
Bukid ilog lawang kay ganda
Sa Castillejos makikita.
Ang bayan kong sinisinta
Ang 'yong ganda'y nagbibigay sigla
Kayang-kaya basta't sama-sama
Ikaw ako tayo magkaisa
Kayang-kaya basta't sama-sama
Ikaw ako tayo magkaisa.
